Novia called Nancy Lanza only once to come to the school, but other administrators frequently requested her presence. She could be at the high school as many as two or three times a week dealing with Adam's behavior issues, Novia said.
But as Adam entered his sophomore year at Newtown High School, Novia thought the boy was making progress.
Adam "would master (technical tasks) very quickly. But still to get him to speak one or two words, it was very, very hard," Novia said. "But over time I was able to get closer and closer to him, to a point where I felt that I could sit next to him and he wouldn't pull away."
He said Nancy Lanza recognized the progress and acknowledged it.
"Yes, she did. She saw it working," he said. "Not just her. Administrators, teachers, all the students that were around him would report that slowly, but surely, he was coming out."
Novia left the Newtown school district after 15 years of service in July 2008. He established a private-investigations company in Spring Hill, Tenn. He said he was stunned to learn after the shootings at Sandy Hook that Nancy Lanza had removed Adam from high school following the boy's sophomore year.
"So suddenly, when she pulls him out of there, he loses all those support groups," Novia said. "He loses the tech club team he was involved in. He loses friends that he had made to a limited degree. He loses his special ed, he loses his school psychologist, he loses the devoted school administrators."
According to a person who has been in touch with Peter Lanza recently, Nancy Lanza never told Adam's father about any frustration with the school. The person spoke on the condition that he not be named.
Novia said he was also surprised that Nancy exposed her son to firearms.
